Embodiments provided a formalized set of intermediate analysis contexts that are relevant for analysis checks of target code. Such intermediate analysis context may include, but are not limited to, the development phase of targeted code, the type or state of the targeted code, a source manipulating the targeted code, a purpose for the targeted code, or other development or runtime requirements. Accordingly, embodiments dynamically identify a current analysis context under which targeted code is being developed and can then execute rules based on knowledge of what contexts the rule(s) may apply. More specifically, analysis rules can describe (e.g., via metadata) those context conditions under which a rule can run. Based on such description and the current context, those rules that have been configured to apply to such context conditions can be executed.

A method and system of identifying one or more nets in a digital IC design that are at risk of electromigration comprises selecting a manufacturing process for the digital IC design and obtaining a clock period and process voltage. A voltage waveform transition time and effective capacitance is calculated for one or more of the nets. A maximum allowable effective capacitance for each one of the nets is calculated based upon a peak current analysis or an RMS current analysis. The effective capacitance for each net is compared against the maximum allowable capacitance to identify those nets that are at risk of failure due to the effects of electromigration.

This invention has two synergistic elements for simultaneous use in point-of-care or field analyses of diverse substances important to clinical medicine and other applications. The first element is a sample holder in which are stored the several reagents need for quantification of target molecules. The onboard storage of reagents in a water soluble plastic obviates the need for purchase, storage, measuring and mixing of the required reagents prior to analyses. The second part of the invention is a compact hand-held analyzer made of modern miniature optical components, into which the holder is inserted right after it is loaded with a sample by capillary action. The combination of the holder and analyzer permits analyses that are ten times faster than those done with current analyzers, and equally accurate. Analyses can be performed by diverse people, who require only a few minutes of training in the use of the entire invention.

While performing functional verification on a circuit design, a verification tool allows a user to analyze the results of a previous functional analysis. The tool may also receive commands for a next verification analysis while performing a current analysis, and it may allow a user to abort a current analysis. Results from a completed analysis may be discarded or saved for viewing by a user while a next verification is performed on the circuit design. This allows a user to continue to debug and analyze the circuit design without having to wait until previous steps in the verification analysis are completed.
